Damn it! I just found my problem. I was using Thread.sleep for postgres reconnection on errors. Probably hit a busy signal and froze the entire app for 10+ seconds. Just did a test to confirm this was my problem.

Sorry man!

Okay, no problem! Actually I was already hoping that this might have
been the same cause as the pauses that occur in the incoming connection
handling under very heavy load, so it would have been nice had this
actually been a bug in the library.
